WHIRLIGIG.

Application filed July 10, 1924.

The object of this invention is to provide a simple, strong and easilyoperated whirligig, more especially designed for the use of children,and adapted for public or private a playgrounds.

The invention is fully disclosed in the description and claimsfollowing, reference being had to the accompanying drawing, in whichFig. 1 is a side elevation of a whirligig embodying the invention, thepivotal mounting of the same being in section. Fig. 2 shows in enlargedsectional detail the preferred construction of the lower end of the l5pivot-post and its bearing.

ln the drawing, the numeral denotes a tubular bearing, which may be oflarge gas-pipe, capped at 6, and set in cement or concrete 8 in theground. T he upper end of the tube extends a little above the upperlevel of the cement7 so as to exclude water from the inside of the tube.ln this tube is mounted the central pivot-post 9 of the whirligig, thelower end of the post resting on the cap at the lower end of the housingtube. Preferably the pivot-post is a piece of smaller gas-pipe, and isprovided with a hemispherical step 10, having a shank 11 fitting tightlyin the pipe, and an annular flange 12 to take the end-thrust. Thehousing being well supplied with grease, the pivot turns veryeasily, andneeds no attention for an .indefinite length of time.

The upper end of the pivot-post fits in a T 18, which is preferably madewith an unthreaded horizontal part 13a to receive the cross-bar 14 as asingle piece of large gaspipe. This is finished at the ends with roundedcaps 15. At suitable intervals,

spaced far enough apart to easily admit a child between them, are fixedsmall upstanding posts 16, of small gas-pipe capped at 1G, which postsare grasped for support by V the children sitting between them. The

" center post, 1Gb may serve as a set screw to hold the cross-barsecurely in place. These posts are all supposed to screw into thecross-bar, which must of course be as- Serial No. 725,294.

sembled in'the T before the posts of one half of the bar can beattached.

To completely exclude water and snow from the housing, the pivot-post isprovided with a tightly fitting bell-shaped cap 17 enclosing the upperend of the housing and depeiding some distance below such upper en Thesize of the whirligig may be such as conditions demand, a capacity of adozen children or so being contemplated for those used in publicplaygrounds. It is to be noted, however, that the cross-bar does notneed to be balanced, the long pivotmaking it easily turnable with anyexcess of weight on one side.

No seats are deemed necessary, the average young child liking nothingbetter than to straddle a pole. There is thus nothing to break or getout of order, and little to hold moisture long after a rain.

Having thus described my invention, I claim z 1. A whirligig,lcomprising a tubular housing securely fixed in the ground, and having abearing-cap at the lower end, a pivot-post mounted revolubly therein,with its lower end bearing on said cap, a crossbar fixed to the upperend of the pivot-post, and a series of spaced upstanding hand-hold postsattached to the cross-bar.

2. A whirligig, comprising a tubular housing capped at the lower end andcemented vertically in the ground, a central pivot-post of tubularmaterial revoluble in the housing` and provided at the lower end with arounded bearing-step, a T secured to the upper end of the pivot-post, acrossbar fixed centrally in the horizontal part of the T, and a seriesof spaced hand-hold posts set vertically along' the length of saidcrossbar. v

3. A whirligig, comprising a tubular housing, capped at its lower end,and set in a concrete foundation in the ground, with its upper endextended abofe the surface, a pivot-post having a stepped lower endbearing on said cap, and revoluble in the housing, a bell-shaped capcovering the post provided at its upper end With a T, a upper end of thehousing and fitting the cross-bar slidable in the horizontal part of 10pivot-post tightly, a cross-bar attached to the T, and a series ofupstanding hand-hold the upper end of the pivot-post by a T, and postsattached to the cross-bar, the central 5 a series of upstandinghand-hold posts disone serving as a set-screw to hold the har posedalong the length of the cross-bar. in place in the T.
